People use envelopes for many different things at home or in the office. They are available in various shapes, sizes, styles and textures. There are those used for personal matters, like birthday invitations and letters, and there are others made for communication between professionals in the workforce. #10 envelopes, specifically, are the perfect choice for all of your business correspondence needs. Read on to learn more about why these are important office supplies for any organization.

What Is a #10 Envelope?

A #10 envelope is used for transactional mail or mail that requires action from the receiver. They are best for things printed on 8 ½” x 11" sheets of copy paper. These vessels are ideal for this type of mail because return envelopes, typically smaller #8 or #9 styles fit perfectly inside. Here are some common applications:

  • Advertising
  • Invoices
  • Utility bills
  • Monthly statements
  • Tax information
  • Checks
  • Contracts
  • Health documents
  • Legal processing

What Features Do #10 Envelopes Have?

Depending on what your needs are, there are many different #10 envelopes suitable for any individual or business. Staples offers a range of color options for those who are looking to put a personal touch on their correspondence with clients. Some #10 envelopes even come with special enclosure flaps and tinted plastic films to ensure that sensitive information is sent securely and efficiently. Read more about these features below.

Security Tint

These are simply a type of #10 envelope that are designed for sending documents containing sensitive information through the mail. They are typically used for documents that handle information involving government correspondence, financial data, medical records or paychecks. In some scenarios, these specialized #10 envelopes protect the sender from being liable for stolen information. For many businesses, this is a best practice that ensures security while delivering documents through the postal service.

Adhesive Strip Seals

Staples offers a variety of #10 envelopes and seal options. Traditional gummed styles are the most commonly used and have a water-soluble gum strip that you moisten to seal. There are also many different types that have adhesive strip seals for those who require an added layer of security. Self-seal and moistenable glue #10 envelopes are equipped with an extra-sticky adhesive that’s ready to peel and go. These seals function as built-in tape and erase any doubts you may have about your mail coming open in transit.

Different Colors

#10 envelopes come in many colors for mail that requires a more personal or creative touch. You can choose from your orange, pink, beige and everything in between. These fun shades help add a personal touch to any business’ marketing campaigns and are also great for individuals sending out invitations that require an RSVP from the guest.
